MATRIX-CASE EQUIPMENT FOR TYPECASTING ).VIAC'JFIINES.'y

To all whom it mayl concern: y p Y Be it known vthat I, FRANK HINMAN Pinn- America, residing at Salfords, Horley, 1n the county of Surrey, England, have invented certain new and useful. Improvements in Matrix-Case` vEquipmentsv for Typecasting Machines; and I do hereby 1declare the following to be a full,` clear, and

vthe matrices Vare supported by or suspended exact description of thesame,l reference being had to the accompanying drawings, forming part of this specification, and to the characters of reference marked thereon. This invention relates to die case or matrix case equipment for typecasting machines and refers more particularly to die cases wherein matrices, ar'ranged'in columns and rows, are supported in such a manner as to limit the motion of the individual matrices laterally, as described for example, in thespecifcation of United StatesLetters Patent No. 784,245, dated March 7, 1905.

. Matrix case equipment of this kind kcomprises oblong matrix blocks, rectangular in cross section and provided with/a character cavity in one end and a conical centering cavity or cone hole in the opposite end for engagement by a centering device bywhich each matrix is pressed orrclamped against the moldwhen a cast is toY be made. The centering device and mold are'parts of a typographic castingk machine well known in the art as manufactured by'Lanston Monotype Machine Company, such machine being basically represented in United States 'Letters Patent No. 625,998,dated MayBO', 1899. A.

The patented matrices 'are provided with transverse grooves on theirfour, side walls within which grooves, when the matrices are assembled in their case, extend parallel supl porting bars and teeth projecting from the bars at right angles thereto, all in a manner ,disclosed in the" patent and well understood by those skilled in theart. 5

The principal object of the present invention is to provide'a matrix case equipment suitable for use in a typographie machine 0f the kind referred to, in which thema- Application filed June 21, 192.3. Serial No. 646,980.

right. yangles to theother and theY case is n:

In accordance with the present invention,

on, a series of parallel ybars preferably rectangular 1n cross section, for the reception ofwhich each matrix is provided in'two of its opposite side walls with external ytransverse grooves,'these bars limiting the movement of the individual matrices in one dlrection. The matrices are also suspended by or supported on, a series of parallel rods v preferably circular in cross section arranged Vat right angles to the suspension bars and forthe reception of these bars, each matrix is provided with a central hole or opening and these rods which limit the movements ofthe individual'matrices in another lat'-v "eral direction, pass'through openings in the suspension bars, interlock.

Since the matrices have only grooves yin -sothat the rods" and bars two walls and have two entire walls .un 'i grooved, alarge and Well distributed bearing surface 1s provided and the suspension bars and rods, which are supported at vtheir ends in suitable bearings in the frame of the v die case, interlock withV one another, and provide rigid supports for the matrices. Referring' to the accompanying drawings Fig, 1 incorporating the present invention.

Fig. 2 is a Section on the line 24-2 of Fig. l. l l

Fig. '3 1s a section on theline 3-3 of Fig.'

' 'Fig 4 is a perspective view of a matrix.

y `*Thematrices are represented by. the character 5, .the suspension bars by the character 6 and the suspension rods by the character 7.

The vvdie case 8 as hitherto comprises a v is an inverted plan of a die case l frame having an opening to accommodate a font or arrangement of matrices. 1t is provided with means of supporting it in the typographie machine and for coupling it with translating or positioning devices thereof. On the rear or top side the usual cover plate or matrix protector 9.

Along tivo of the opposite sides of the die case the Walls surrounding the matrix receiving space, are each provided With a series of slots or grooves 10 to receive the parallel suspension bars 6, (see Figs. 1 and 2), and in the t-Woremaining Walls are formed openings or holes l1 for the reception of the ends of the cylindrical suspension rods 7. The holes 11 in one Wall are of practically the same diameter throughout as the suspension rods and extend through the Wall so that. the rods can be inserted through them from the exterior of the die case. The holes 11 in the opposite Wall are at their inner endso the same diameter as the suspension rods but this diameter is not continued to the outside of the Wall so that shoulders .12 are formed Which constitute stops for the ends of the rods. The holes are continued of smaller diameter to the outside of the Walls to permit ot the insertion of a Wire or the like for pushing the 'suspension rods out. rllhe rods are held in Vthe grooves 15 each matrix has a central hole or opening 16 of slightly larger diameter than the suspension rods 7.

The suspension bars are each furnished with a series of holes 17 for the passage ot the suspension rods 7.

The suspension bars-Gare placed between rows of matrices 5- before the latter are placed in the die case and. When thc bars 6 and matrices 5 are placed in the die case the ends of the bars 6 rest in the slots 10 in the Walls ot. the die case and prevent or limit the. movement of the matrices in one direction. After the matrices 5 and bars6 have been. placed in the die case, the suspension rods 7 are inserted so that they pass through the holes 17 in the bars 6 and the central holes 16 in the matrices 5 and. prevent or limit the movement of the individual matrices in a direction at right angles to the direction controlled bythe bars 6.

By` means of. the bars 6 and rods 7 each matrix is individually supported and. lateral movement in both directions is limited or prevented.

The sides of the matrices Which have the grooves 15 have portions 18 of the original Walls lett at the upper and lower ends of the matrices and these portions serve as bearing surfaces to prevent or minimize the tendency of the matrices to turn or tilt. The remaining tivo Walls 19 ot the matrices have the entire original surface leftto form bearing surfaces for the same purpose. Thus larger and better distributed bearing surfaces are provided than with matrices as that the bars are simpleflat plates,.rectan gular in crossy section, With holes drilled through them and that the matrices are also easy and inexpensive to manufacture..
